Solution

In this specific case (as listed below), the ingress/egress ports are non-ifd. ACX7100 does not support mirroring on IFLs. The solution is to use IFDs instead of IFLs.

 

user@host> show configuration forwarding-options analyzer | display set

set forwarding-options analyzer TCPDUMP input ingress interface ae0.2001

set forwarding-options analyzer TCPDUMP input egress interface ae0.2001

set forwarding-options analyzer TCPDUMP output ip-address 192.168.0.201
